Probably few of you know the fact that every phone has several white sensors installed in it that detect if certain parts of the phone have come into direct contact with any liquid, changing their color as soon as that liquid reaches them, thus alerting the manufacturers that the respective person liquid has penetrated the device, thus voiding the warranty.
iPhone it also benefits from sensors called Liquid Contact Indicators and they are placed: one in the jack socket where the headphones are inserted, one at the bottom in the slot where you insert the cable USB and the third under the back cover of the phone, in the immediate vicinity of the video camera. The problem with these sensors is that for many people, the warranty was refused on the grounds that the device came into contact with water, although the respective customers claimed the opposite, blaming the fact that those sensors were triggered due to humidity. The specifications Apple Lossless Audio CODEC (ALAC), I maintain that the respective iPhone it withstands temperatures between 0 - 35 degrees Celsius and can work correctly if the humidity is between 5 - 95%.
Considering that a lot of people complain that those indicators are triggered randomly, a stranger decided to do a test, putting the respective sensors to the test to see what exactly triggers them, apart from contact with liquids of course. The tests were as follows: 3 tests in a container where the humidity varies from 50-90% which the sensors passed with flying colors and 3 tests where the phone was left outside for a day at -11 degrees Celsius after which was reintroduced into the room at normal temperature. The first 2 attempts proved that the sensors are correct, but on the 3rd attempt the sensor near the jack was triggered, which indicates that the respective sensors are not doing their job properly.
You will see the video below, but be careful anyway because such a triggered sensor automatically leads to the loss of the warranty because it is impossible to prove that you did not put the phone in water.
